Bangladesh’s Defence Ministry is seeking responses to a tender for five patrol craft for the country’s navy.
According to the tender, the patrol craft should have a proven design with a length of approximately 50–52 m, a beam of 7–8 m, a maximum draught of 2 m, and a displacement of between 270 and 320 tonnes. It should be steel-hulled with an aluminium superstructure.
The vessel should be powered by two diesel engines driving two shafts, and an electrical power generation equipment that would need to be of ‘western origin’. Weapons to be mounted on the craft include a Type 61 twin 37 mm gun, and two 20 mm Oerlikon cannons.
